  2. 6. - The pericardium is a double-layered sac that surrounds and protects the heart.
  3. 9. - An artery is a type of blood vessel that carries blood away from the heart, typically oxygenated, except for the pulmonary arteries, which carry deoxygenated blood to the lungs.
  4. 11. Artery- It is the only artery in the body that carries deoxygenated blood (arteries usually carry oxygenated blood).
  5. 12. An atrium (plural: atria) is one of the two upper chambers of the heart that receives blood returning to the heart from the body or lungs.
  6. 13. - White blood cell which plays a vital role in the body’s immune defense system.

  2. 3. - A capillary is the smallest and thinnest type of blood vessel in the body, responsible for exchanging gases, nutrients, and waste between the blood and surrounding tissues.
  3. 4. - A thrombocyte, also known as a platelet, is a small, disc-shaped cell fragment in the blood that plays a key role in hemostasis, the process that stops bleeding.
  4. 5. -A vein is a type of blood vessel that carries blood toward the heart, usually deoxygenated, except for pulmonary veins, which carry oxygenated blood from the lungs.
  5. 7. A ventricle is one of the two lower chambers of the heart responsible for pumping blood out of the heart — either to the lungs or the rest of the body.
  6. 8. Cava- A thrombocyte, also known as a platelet, is a small, disc-shaped cell fragment in the blood that plays a key role in hemostasis, the process that stops bleeding.
  7. 9. - The aorta is the largest artery in the human body. It carries oxygenated blood from the left ventricle of the heart to the rest of the body.
  8. 10. vein- The pulmonary vein is a blood vessel that carries oxygenated blood from the lungs to the left atrium of the heart.
